To all whom it may concern.-

Be it known that I, EDOUARD DEOOCK, a citizen of the French Republic, residing at Roubaix, (Nord,) France, have invented certain new and useful Improvements in Machines for Dyeing Textile Materials in Hanks, (for which patents have been granted in France, No. 208,508, dated October 2, 1890; in England, No. 7,511, dated April30, 1891; in Germany, No. 61,282, dated April 11, 1891; in Switzerland, No. 12,640, dated June 13, 1896, and in Austria, No. 46/3,67l, dated September 22, 1896,) of which the following is a specification.

My invention relates to machinery for dyeing textile materials in hanks so arranged that all the operations are effected automatically from the introduction of the materials into the bath until their removal from the bath after the dyeing has been completed, the materials being prevented from turning until they are removed from the bath, so that they are always held straight and are not liable to felting. The machinery is for this purpose constructed as shown on the accompanying drawings, in which-- Figure 1 shows a side elevation; Fig. 2, an end elevation, and Figs. 3 to 7 separate modified details.

In this machine the hanks descend vertically into the bath and are then conveyed horizontally partly through the same at a quick speed by means of two small chains 0 with fingers, after which they are taken by two larger horizontal chains withfingers P, which travel at a slower speed. By this means a more reliable penetration of the dye into the body of the hank is obtained, as without the rapid motion at the entrance into'the bath the dye only acts effectually on the surface of the banks, leaving the interior imperfectly acted upon. In other words, by the rapid motion the hanks are opened out, so as to allow the dye to come in contact freely with all parts.

The transport of the banks through the bath without rotary motion prevents felting and entanglement of the threads, which occurs in other methods of dyeing, while it insures the stirring up of the bath and gives a greater and more regular yield for one and the same quantity of dissolved coloring-matter.

The textile matter to be dyed in hanks is suspended and prepared on hank-carriers of rectangular cross-section which are made to slide down into the machine upon two beams 0, supported by hinge-joints at D on uprights B, fixed to the framing of the machine. When the hank-bearers arrive at the lower end of these beams 0, they are seized, first, by projecting fingers or abutrnen ts of the verticallyrising chains L, then by the fingers of the horizontal traveling chains M, and, lastly, by those of the vertically-descending chains N, which carry them down into the bath. Here the bearers are again seized by the fingers of the horizontal chains 0, by which they are conveyed rapidly to the fingers of the horizontal traveling chains P, which, as before stated, move at a slower speed in order to insure a gradual and enduring action of the bath upon the material to be dyed. On being discharged from the chains P the hank-bearers passon to circular guide R, where they are again taken up by the fingers of the chain L, which carry them 'up to the chain M again, and thus cause the above-described operation to be repeated. Inpassing along with the chains M the toothed pinions on the ends of the hank-carriers come into gear with toothed racks S, which in rotating the pinions as they pass along also effect the turning over of the next immersion in the bath, so that the por' tion of the hank which before was situated above the bath is now immersed in the same. This operation is repeated a sufficient number of times for effecting the perfectly uniform treatment of all parts of the hank by the bath, after which on arriving at the lefthand end the hanks are made to slide along the inclined plane Z outside the machine.

The arrangement of pinions U, Fig. 1, toothed racks T, fast and loose pulleys; A B G, worm-wheel, and worm E D allows of the raising up out of the bath of the whole of the dyed hanks when itis found thatthe dye of the bath is not sufficiently edective, in order that the bath may be renewed, after which the hanks are again lowered into thesame,

The above-described mode of treatment relates to hanks of cotton thread. For woolen hanks the form of hank-bearers shown in elevation and cross-section at Figs. 3 and 4 is employed. This consists of two parallel wooden trough-shaped bars a a, kept apart by metal caps d 01, through slots in which passes a spindle e, so that the bars a a in being turned around on the spindle alternately rest with their hollows upon the latter, as shown. These bearers in being carried along by the upper chain M meet with a series of three or more obstacles arranged and operating as shown at Fig. 5 and which take the place of the racks S of the first arrangement. The hank-carrier in being moved along by the chain in the direction from the right to the left first comes in contact with two fixed curved cam-plates T, which raise it somewhat in an inclined position, after which it comes in contact with cranked stops U U, pivoted at X. The hank-bearer in being brought by the fingers of the chain in contact with the vertical arm U, as shown at the right-hand end,cants this over, as shown at the middle position, while at the same time the arm V in rising into the position shown at the left-hand end completes the turning over of the hank-bearer. This operation being repeated three or more times, according to the number of the stops, it will be seen that the hank will be made to travel around the bearer to a corresponding extent.

The above-described machine has continuous action. If it be desired to render the action of the machine intermittent-that is to say, with a period of rest for the hanks while in the bath-at a desired time, driving-gear arranged as shown in end and side views at Figs. 6 and 7 can be employed. In this arrangement a pulley I, free to slide on a sleeve that is loose on the shaft K, has a neck g and a serrated disk h, whereby it can be coupled at times with a collar 76, fixed on the shaft K. A fork e, embracing the neck 9 and turning on a horizontal pivot o, is urged by an arm carrying a weight m, so as to tend to keep the pulleyI geared with the collar 70 and consequently with the shaft. The fork has a horizontal arml projecting with its end into a cam-groove in a disk Q, which is so formed that at a certain point or points of its revolution it pushes the fork, and with it the pulley, to the left against the action of the weight, which rises, and the pulley is then disengaged from the shaft and runs loose thereon. Thus the pulley I being driven by a strap and corresponding to the pulley I in Fig. 2 it will be seen that during the part of the revolution of the cam Q at which it allows the pulley I to gear with its shaft K the endless chains 0 P will be driven by the latter and the hanks will be made to travel through the bath, while during the time that the cam throws the pulley out of gear with its shaft the hanks will remain stationary in the bath.

The cam-disk Q, the speed of which governs the duration of the above-named intervals, is driven at a. slow speed from the boss of the pulley by a worm r on the latter gearing with a Wheel g on a counter-shaft carrying a worm n, gearing with a worm-wheel p on the camshaft.

In machines that require to give a large production the chains P and M would become too long if formed in one length, as described, and in extending by wear would produce irregularities in the working. They are consequently in such cases divided into two or more separate endless chains, the contiguous ends of which pass round two chain-wheels fixed closely side by side on the same axis, the fingers of the chains being so arranged that those of the one length take up the hankbearers of the previous length as the two chains pass round the wheels. If desired, there may be interposed between two successive endless chains P, having a slow speed, an endless chain 0, having a quick speed, in order thereby to again effect the opening out .of the hanks, so as to increase the penetration of the dye-bath at an intermediate stage of the operation.

In order to insure the regular passage of the hank-carriers from the chains P tothe circular guide R on issuing from the bath,

R, where they are caught by the fingers of' the chains L. When the requisite number of hank-carriers have been fed into the bath along the incline O, as described, this is turned up out of the way of its hinge-joint D, and the curved guide R is then turned up on its hinge and secured by a pin, so as to form a complete closed path, in which the hank-carriers travel upward on the chain L. In like manner when the hank-carriers require to be conveyed down into the bath again by the chains N at the left-hand end the guides R are secured in the position shown to form a closed path, and when the treat ment is completed and the hanks require to be discharged down the incline Z, as stated, the guide R is unfastened and turned down on its hinge-joint.

In order'to insure the motion and relative position of the chains shall always remain identical notwithstanding the raising and lowering thereof previously described, the shafts that drive the chains 0 and P are connected by bevel-gear to vertical shafts N N, on which are bevel-pinions 5, carried round thereby, but capable of sliding with a feather and groove vertically thereon and which are kept in gear by their weight with bevel-pinions 6, fixed on the axes of the pitch-wheels that drive the chains N, which in their turn drive the pitch-wheels of the chains M and L. Thus in whatever raised or lowered position the chains may be they will always be kept correctly geared together by means of the pinions 5, and consequently the fingers of the one chain cannot get shifted out of the correct position relatively to the others.
